Since it was me who initially raised that bug, I feel like I should comment on this.
My test case was and is to install Ubuntu on z/VM using (at least one) zFCP/SCSI devices for disk storage. That should be a proper end-2-end test since it includes the entire zFCP/SCSI stack (even incl. multipath) and with that covers the initially reported problem mentioned in the bug description. Please notice that all this happened to me on 16.04(.5) only with GA kernel 4.4 (hence the '4.4' still in the headline and even 16.04's HWE kernel 4.15 worked for me in the past - see comment above), but now it looks like we talk about 18.04 too, but I never saw that problem on 18.04. Nevertheless, I (re-)tested today on 18.04(.3) - so it's more a regression test than anything else. I used 18.04.3 default (means proposed disabled) as well as with proposed enabled. W/o proposed I see systemd 237-3ubuntu10.29 with propose I see 237-3ubuntu10.31. Means I wasn't able to use 237-3ubuntu10.30 - like mentioned in comment #30. But both tests worked fine for me and I didn't saw any anomalies (details see attachment). ** Attachment added: "verification bionic.txt" https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1784454/+attachment/5293039/+files/verification%20bionic.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1784454 Title: kernel panic on booting kernel 4.4 based d-i from 16.04.5 RC image Status in Ubuntu on IBM z Systems: Fix Released Status in debian-installer package in Ubuntu: Fix Released Status in linux package in Ubuntu: Invalid Status in systemd package in Ubuntu: New Status in systemd source package in Xenial: Fix Released Status in systemd source package in Bionic: Incomplete Bug description: Booting d-i based on kernel 4.4 (from ./boot folder) from the 16.04.5 RC image on a z/VM guest leads to a kernel panic: /lib/debian-installer/start-udev: line 15: can't create /sys/module/scsi_mod/par ameters/scan: Permission denied ¬ 0.845071| Kernel panic - not syncing: Attempted to kill initÜ exitcode=0x00 000100 ¬ 0.845071| ¬ 0.845075| CPU: 0 PID: 1 Comm: /init Not tainted 4.4.0-131-generic #157-Ubun tu ¬ 0.845077| 000000007d107c20 000000007d107cb0 0000000000000002 0000000 000000000 000000007d107d50 000000007d107cc8 000000007d107cc8 0000000000114732 000000000000008b 00000000009a304c 00000000009f11d0 000000000000000b 000000007d107d10 000000007d107cb0 0000000000000000 0000000000000000 0400000001cdf800 0000000000114732 000000007d107cb0 000000007d107d10 ¬ 0.845089| Call Trace: ¬ 0.845093| (¬<000000000011461a>| show_trace+0xfa/0x150) ¬ 0.845095| ¬<00000000001146e2>| show_stack+0x72/0xf8 ¬ 0.845099| ¬<0000000000555752>| dump_stack+0x82/0xb8 ¬ 0.845101| ¬<0000000000286390>| panic+0x108/0x250 ¬ 0.845104| ¬<0000000000166228>| do_exit+0xac0/0xba0 ¬ 0.845106| ¬<00000000001663c8>| do_group_exit+0x50/0xe0 ¬ 0.845108| ¬<0000000000166488>| __wake_up_parent+0x0/0x28 ¬ 0.845111| ¬<00000000007eadda>| system_call+0xee/0x28c ¬ 0.845113| ¬<000003ff8953983a>| 0x3ff8953983a 00: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 0010F8CA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1784454/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
